As the creater puts it in the README, this is a "VERY old doom1 episode". The WAD might have been made in 1995, but on the /idgames/ archive it says 1998, so that's what I'm going with.
The WAD is very old, and if you're more used to new mods for Doom made in say the past few years, then you won't like this mod at all, but if you're a fan of older mods than check this one out.
You should also check out mystican's website, it's been offline since around 1999, but it pure 90's gold, you can find the site on the archive.org mirror, but make sure you're using Netscape or IE4, as his site was "designed with netscape in mind"!
I've also added a screencap of the ENDOOM screen as many ports don't bother to show it at all.
